SPECIFICATION forming part of Letters Patent No. 223,376, dated January6, 1880.

l Application filed February 11, 187B. i

To all whom fit may concern Be it known that I, STEPHEN S. NEWTON, ofBinghamton, in the county of Broome and State of New York, have inventedcertain new and useful Improvements in Lamps; and I do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompany ing drawing, and to the letters of reference marked thereon,which form a part` of this specification.

My invention relates to that class of lamps which have an inclosingshell or casing, serving as a drip to collect oil, which would, were itnot for such shell, run down the outside of the lamp and soil whateverit stands upon.

The object ot my invention is to cheapen their construction, to renderthem more safe from explosion, and to make them more ornamental.

Thedrawing is a vertical section of a lamp embodying my invention.

A represents the outer portion or inciosingshell, provided, preferably,with a standard, A', connecting it with a suitable base, (not shown;)but, when desired, the lower part of the body A may be expanded into a`suitable shape to rest upon a table or other support.

a is a screw-thread, formed upon the outer upper part ofthe shell Aduring the operation of lolowing` the same.

c is a rib, also formed upon the part Ajust below the screwthread a.

B B is the inner portion, or reservoir or fount, the outline of itslower part corresponding substantially to that of the inside of theshell, but of less. diameter.

I usually make the 'ount so much smaller than the shell A as to leave anannular space of, say, one-quarter of an inch between them, which spaceI pack with iiielysliredded asy bestus or some other non-conductingabsorbthe absorbing material and the cleansing of the shell. 1 r

By preference the fount is made of metal, in two pieces, B B', eachstruck or stamped from a single piece, and soldered together at b.

rIlhe part B' is provided with a neck or burner-socket, B2, and has aflange, b', screwthreaded internally to engage with the screwthread a of'the shell A, the width of this iange being such that its lower edgeshall rest upon the rib a when the parts are in proper positiomand thuspresent a nished appearance at this point.A

b2 b2 are openings in dan ge b', through which oil passes into theannular space below.

Although I prefer to make the fount of metal, and to form the flange bin one piece with the part B ot' said fount, yet it is apparent that it(the t'ouut) may be made of glass, in which case I would make the iiangeb of metal, when,.by screwing it upon the thread a, the fount may befirmly held in place. In using this latter construction I would preferto support the fount upon the shell A by means of lugs or otherequivalent devices, in order to insure a tight and permanent tit at thejunction of the flange b with the part represented by B', these lugsholding the upper face o f the part B in close contact with the underside of the flange b.

The use of the lugs facilitates the introduction of the packingmaterial, because they insure the formation ot' an annular space ofsubstantially uniform width between the fount and the shell, and alsoserve to keep the upper edge of the fount in the proper plane relativeto the plane of the upper edge of the shell during the operation ofputting in the packing, and when the fomit B B is made of metal, thelower part, B, may be made of cheaper material than the part B andtlange b; or these latter parts B b may be plated, and thus renderedornament-al.

By reason of the shell being made in one piece and of such size at itsupper end that the fount can be inserted therein, the annular spacebetween them can be readily filled with the packing material, which canbe pressed into the required density, after which the flange can bescrewed into place. y

What I claim is- IOO 1. In a lamp, an inolosingsheil provided at itsupper edge with a screw-thread, in combination with a fount arrangedwithin said shell, and a screw-threaded ring separate and apart from thefount, which secures said fount Within the shell, substantially as setforth.

2. In a lamp, the combination of-t'he inolosing-shell A, fonnt B B',provided with lugs b3, flange b', and a packing of absorbent materialinterposed between the fount and the inolosing-shell7 substantially asset forth.

3. The combination of the shell A, provided l with the rib a', the fountB, and the screwthreaded angel, arranged with its lower edge abuttingagainst the rib a', substantialiy 15 as set forth.

4. The combination of the shell A,1ugs b3, fount B, and a flangeengaging with the upper edge of the shell to receive the fount inposition, substan tialiy as set forth. l

In testimony that I claim the lforegoing as my'own I affix my signaturein `presence of two Witnesses.
